TITLE: COMPACT UTILITY TYPE SURFACE CLEANING VEHICLE
INVENTOR: ROGER VANDERLINDEN
r ' CA 02317098 2000-08-10 FIELD OF THE INVENTION
The present invention relates to surface cleaning vehicles and more particularly to utility type surface cleaning vehicles.
BACRGROOND OF THE INVENTION
The removal of dirt and debris from streets, parking lots, airport runways, factory floors, and other similar paved surfaces, through the use of various types of street cleaning vehicles or factory sweeping vehicles, as may be the case, has been known for many years. For the sake of brevity, clarity and simplicity, such vehicles will be generally referred to in this document as surface cleaning vehicles.
Conventional surface cleaning vehicles comprise a surface cleaning mechanism, such as a sweeping broom, a recirculating air type air head, or a vacuum air head. Most commonly, such surface cleaning mechanisms are permanently mounted on a truck frame.
Alternatively, such surface cleaning mechanisms are removably connected to a tractor, either securely attached to the three point hitch for direct turning with the tractor, or connected in freely ' " CA 02317098 2000-08-10 pivoting relation to the towbar. The tractors being referred to are typically conventional unitary frame -- or in other words are non-articulated -- utility type tractors, manufactured by companies such as Ford, John Deere, Massey Ferguson, among others. Such conventional tractors are powered by an internal combustion engine that typically can produce about sixty-five to seventy horsepower.
Utility type surface cleaning vehicles have inherent cost and overall operational advantages over truck type surface cleaning vehicles in that the tractors can additionally be used to perform other tasks, such as ploughing snow, cutting grass, and so on.
However, in spite of these advantages that are extremely important to the owners or operators of such vehicles, utility type surface cleaning vehicles are much less popular than truck type surface cleaning vehicles largely due to their overall performance, And also due to their slow maximum speed while travelling between work sites.
A serious drawback with utility type surface cleaning vehicles is that the main surface cleaning apparatus -- excluding the gutter brooms, the debris hopper, and the debris transfer apparatus are all positioned behind the tractor, and the gutter brooms are positioned in front of the tractor. Accordingly, the overall vehicle is quite long, which means that is difficult for such utility type surface cleaning vehicles to safely and properly ' ' CA 02317098 2000-08-10 manoeuver around objects on a city street, to accurately turn corners in a city block while maintaining one gutter broom properly against a curb, and so on. Further, it is extremely difficult, to turn around such a utility type surface cleaning vehicle in a dead-end street, which is unacceptable.
In some utility type surface cleaning vehicles, both the gutter brooms and the hopper are located behind the tractor portion. Accordingly, the overall vehicle is extremely long, thus making it even more difficult to manoeuver Further, during the operation of the surface cleaning vehicle, it is necessary for the operator to look in a rearward direction in order to watch the main surface cleaning apparatus and to properly follow the curb. This is potentially dangerous since it is necessary for the operator to look in a forward direction in order to watch the road in general and to view the gutter brooms, to ensure that the gutter brooms are disposed in contacting relation with the curb. Accordingly, in a utility type surface cleaning vehicle, it is very undesirable to have the main surface cleaning apparatus disposed behind the tractor.
It is therefore very important that utility type surface cleaning vehicles are as short as reasonably possible.

Figure 2 is a top plan view of the preferred embodiment utility type surface cleaning vehicle of Figure 1; and, Figure 3 is a top plan view of an alternative embodiment utility type surface cleaning vehicle according to the present l0 invention.
DETAILED DESCRIPTION OF A PREFERRED E~ODI~NT
Reference will now be made to Figures 1 through 3 of the drawings, which show a preferred embodiment and an alternative embodiment of the utility type surface cleaning vehicle according to the present invention.
Reference will first be made to Figures 1 and 2, which show a preferred embodiment utility type surface cleaning vehicle, as indicated by the general reference numeral 20. The utility type surface cleaning vehicle 20 includes a unitary frame -- or in other words non-articulating -- utility type tractor, as indicated by the general reference numeral 30, having a front end 32 and a back end 34, and a frame 31 which defines a longitudinal axis "A". An internal combustion engine 35 that produces about sixty-five to seventy horsepower is mounted within an external engine housing 36 forming part of the unitary frame utility type tractor 30. A
manual transmission 40 is connected in driven relation to the internal combustion engine 35, with the robust housing 42 of the manual transmission 40 forming part of the unitary frame utility type tractor 30. A rear differential 44 is connected in driven relation to the manual transmission 40 and also forms part of the unitary frame utility type tractor 30. Alternatively, the unitary frame utility type tractor 30 could be hydraulically driven. A
power take-off mechanism 45 is operatively mounted on the utility type tractor 30. More specifically, the power take-off mechanism 45 is connected in driven relation to the internal combustion engine 34. Trailer connecting means comprising a three-point hitch 46 and/or a towbar 48 are mounted on the frame 32 of the tractor 30.
There is at least one steerable front wheel, as indicated by the general reference numeral 70, and in the preferred embodiment as illustrated, there is a left front wheel 72 and a right 74 front wheel 74. The left 72 and right 74 front wheels are ' ' ' CA 02317098 2000-08-10 mounted on the frame 31 for free rotation about a substantially horizontal front wheel pivot axis "PF", and are steerable by means of the tractor's steering wheel 21 such that the front wheel pivot axis moves angularly with respect to a substantially vertical steering axis "S" between an extreme left angular orientation and an extreme right angular orientation. Analogously, the tractor may have a standard fixed front axle with left and right wheels mounted at the opposite ends thereof for co-operating turning about spaced apart axes.
Left 76 and right 78 driven rear wheels are mounted on the frame 31 at the rear differential 44 for selectively driven rotation about a substantially horizontal rear wheel pivot axis "PR", as powered by the internal combustion engine 35.
Such tractors 30 are typically used in agricultural applications and on construction sites, for low speed carrying, pushing, or pulling of implements. For the purpose of this document, the terms "tractor" and "tractors" do not include truck-type tractors used to pull transport trailers and do not include trucks.
Left 82 and right 84 gutter brooms are each mounted on the surface cleaning vehicle 20 for rotation about substantially vertical left and right gutter broom axes "LA" and "RA", ' ' ' CA 02317098 2000-08-10 respectively. Preferably, the left 82 and right 84 gutter brooms are disc-type brushes and are selectively moveable between a lowered surface cleaning position, as can be seen in Figure 1, and a raised position, which is not specifically illustrated. The left 82 and right 84 gutter brooms are mounted such that the left "L"
and right "R" gutter broom axes are disposed entirely rearwardly of the foremost portion of the left 72 and right 74 steerable front wheels, when the front wheels 72,74 are straight. Further, the left 82 and right 84 gutter brooms are mounted forwardly of the left 76 and right 78 driven rear wheels so as to not interfere with the driven rear wheels 76,78.
In the preferred embodiment, as illustrated, the left 82 and right 84 gutter brooms are each mounted on the surface cleaning vehicle 20 so as to be disposed entirely rearwardly of the left 72 and right 74 steerable front wheels, and disposed immediately forwardly of the driven rear wheels 76,78.
A main surface cleaning apparatus that, in the preferred embodiment as illustrated, comprises a recirculating air type pick-up head 52, is operatively mountable via mounting brackets 53 (only one viewable) in removable relation on the unitary frame utility type tractor 30 so as to be disposed there-beneath between the front end 32 and the back end 34 of the tractor 30. Preferably, the pick-up head 52 is mounted between the front wheels 72, 74 and " " ' CA 02317098 2000-08-10 the driven rear wheels 76, 78, so as to extend laterally outwardly from each of the left and right sides of the frame 31.
The recirculating air type pick-up head 52 receives a stream of air from a main fan 54 through a removably mountable air supply hose 56. The recirculating air type pick-up head 52 includes a cylindrically shaped rotating sweeping broom 57 powered hydraulically by means of a pump 43 mounted on the power take-off mechanism 45 through hydraulic hoses (not shown).
A trailing unit, as indicated by the general reference numeral 50, is removably mountable to the surface cleaning vehicle via the three point hitch 46. In this case, the weight of the trailing unit 50 is borne partly, or even mostly, by the frame 31, and partially by wheels 49. Also, the trailing unit 50 would turn with the tractor 30, with the back end of the trailing unit 50 extending outwardly in the opposite direction to the direction of turn of the tractor 30. Alternatively, the towbar 48 could be used, but with any unit towed via the towbar 48, the weight of the trailing unit 50 is borne mostly by wheel means mounted on the trailing unit 50, and accordingly, the trailing unit 50 would be towed in freely pivotal relation about the hitch portion 47 of the towbar 48.
In either case, the trailing unit 50 includes a debris hopper 58 that is thereby removably connectable to the unitary frame utility type tractor 30 so as to be disposed rearwardly of the frame 31, with the main fan 54 mounted thereon.
The trailing unit 50 also includes a debris transfer means comprising a suction hose 62 mounted in removable relation on the unitary frame utility type tractor 30. The suction hose 62 is in fluid communication with the recirculating air type pick-up head 52 and the debris hopper 58. The recirculating air type pick-up head 52 is thereby connected in debris depositing relation, via the suction hose 62, to the debris hopper 58. The debris hopper 58 thereby receives debris from the recirculating air type pick-up head 52.
In an alternative embodiment of the utility type surface cleaning vehicle according to the present invention, as indicated by the general reference numeral 100 in Figure 3, the main surface cleaning apparatus comprises a windrow broom 102 disposed in transversely angled relation beneath the frame 104. The windrow broom 102 feeds a vacuum type pick-up head 106 disposed at the right side of the frame 104. Debris is gathered by the vacuum type pick-up head 106 and is suctioned through the suction hose 108 to the debris hopper 110, as powered by the main fan 112 mounted on ' ' CA 02317098 2000-08-10 the hopper, for expulsion to the ambient atmosphere, as indicated by arrow "B" .
Other variations of the above principles will be apparent to those who are knowledgeable in the field of the invention, and such variations are considered to be within the scope of the present invention. Further, other modifications and alterations may be used in the design and manufacture of the apparatus of the present invention without departing from the spirit and scope of the accompanying claims.
It is an obj ect of the present invention to provide a utility type surface cleaning vehicle that is easier to manoeuver than prior art utility type surface cleaning vehicles.
It is another object of the present invention to provide a utility type surface cleaning vehicle wherein the main surface cleaning apparatus is not disposed behind the tractor.
